AD5755-1ACPZ-REEL7

Overview

The AD5755-1 is a quad-channel, 16-bit digital-to-analog converter (DAC) featuring simultaneous voltage and current outputs. It operates with power supplies ranging from −26.4 V to +33 V and includes on-chip dynamic power control to minimize thermal dissipation in current mode by regulating the output driver voltage between 7.4 V and 29.5 V. The device supports HART connectivity via dedicated CHART pins coupled to each channel's current output. It utilizes a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, DSP, and microcontroller standards, operating at clock rates up to 30 MHz.

Feature Summary

• 16-bit resolution with guaranteed monotonicity and ±0.05% maximum total unadjusted error (TUE) for current outputs.
• Integrated dynamic power control using a DC-to-DC boost converter to regulate output driver voltage from 7.4 V to 29.5 V.
• Dedicated CHART pins allow direct coupling of HART signals onto the current output terminals.
• User-programmable offset and gain registers enable precise calibration without external components.

Applications

• Process control systems
• Actuator control loops
• Programmable logic controllers (PLCs)
• HART network connectivity interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure that the selected variant matches the required temperature range and pin configuration for the target application design.

Selection Notes

Select this component when high accuracy and HART protocol support are required in a multi-channel environment. Consider the internal RSET versus external RSET options based on desired TUE performance and thermal management requirements within the system constraints.
